The present invention relates to a coating composition and a method forcoating using the same, and more particularly, the present inventionrelates to a coating composition and a method for coating using the samefor preventing adhesion of advertising materials by being coated onpublic or private facilities, such as walls, poles, street lights, ortraffic lights, for the purpose of preventing attachment of unlawfuladvertising materials.

BACKGROUND ART

Generally, the poles for street lamps, road signs, traffic signals, andpower transmission are installed at places having very good visibility.Accordingly, they attract attachment of unlawful advertisementmaterials.

Other road facilities installed at highly-visible locations furtherinclude fences and breast walls, which are also exposed to adhesion ofunlawful advertising materials.

Unlawful advertising materials are one of the major sources whichdeteriorate urban environment. The leaflets and posters posted onvarious private and public facilities without due authorization defilethe appearance of the street, especially, those attached on the surfaceor posts of traffic signs can be a cause of traffic accident bydistracting drivers from driving or deteriorating the communicationcapacity of the traffic signs.

In the mean time, many local governments are operating a dedicated teamfor removing such unlawful advertising materials on a continuous basis,however, fail to provide a fundamental solution due to high cost.

To this end, plates or sheets which can prevent unlawful advertisingmaterials from being attached on street lights, road signs, and trafficsignals installed along on the roads are suggested.

Examples of the sheets for preventing unlawful advertising materialsinclude a sheet made of rubber or a synthetic resin, formed withconical, quadrangular pyramidal, or similar projections on one surface,and the sheet wraps around a post of street light, road sign or trafficlight and fastened with one or more additional bands.

However, this configuration requires additional bands and fasteners tofix the sheet, and defiles the appearance of the street with the exposedbands and fasteners, not mentioning the structural complexity.

The first coating composition, when coated on private orpublic installations, forms very small irregularities on the driedsurface to allow easy removal of advertising materials attached on thecoating sheet in accordance with the present invention without using amechanical means such as a scrapper. The first coating composition canbe coated on public or private installations such as walls, poles,street lights and traffic lights by air spraying or roller coatingmethod. The public or private installations may be made of a materialhaving a soft surface, for example, PVC, or metallic materials.

The first coating composition may comprise: 25 to 35 parts by weight ofurethane resin solution, acrylic resin solution, or epoxy resinsolution; 5 to 35 parts by weight of urethane pigment, acryl pigment orepoxy pigment, 10 to 20 parts by weight of PE-thermoplastic resin beads,phenol resin beads, melamine resin beads, epoxy resin beads, polystyreneresin beads or glass beads having a wide range of diameters between from10 to 500 μm; 40 to 52 parts by weight of urethane thinner and toluene;and 2 to 4 parts by weight of curing agent for increasing hardness orpromoting hardening. The curing agent can be isocyanate TDI (toluenedi-iso cyanate), MDI (methylene diphenyl di-isocyanate) urethanesynthetic resin, diethylenetriamine (DETA), TET(Tetramethylthiurammonosulfide), acrylic, or epoxy curing agent.

In addition, the urethane pigment, acryl pigment or epoxy pigment can betransparent or have various colors so that a desirable color can beselected and used to match the color of the private or publicinstallations in order not to defile the appearance of the street.

Of the coating compositions in accordance with the present invention forpreventing adhesion of advertising materials, the first coatingcomposition can further comprise a silica curing agent. The silicacuring agent used in cold seasons can be added to reduce curing time anddrying time of the composition of the first coating layer at an ambienttemperature between from −1 to −20 degrees Celsius. For the purpose ofthe present invention, the silica curing agent can be added by from 4 to8 parts by weight.

In addition, the first coating composition can further comprise fineparticles of luminous paint. The luminous paint particles are added toenhance visibility of the installations at night by reflecting light.The particle size ranges from between 50 to 250 μm and the concentrationranges from between 10 to 15 unit weight per 100 unit weight of thefirst coating composition. In the present invention, the luminous paintparticles can be zinc sulfide containing copper added with radium oralkaline earth metal sulfide or zinc sulfide added with a heavy metal.In the present invention, the small irregularity formed on the curedcoating layer of the first coating composition and the light reflectedby the luminous paint particles improve releasability and visibility ofinstallations.
